Lightroom Classic 14.1 Modifying the mask created by the adaptive blur background preset

[ahazel]

I am using the blur background adaptive preset.  But it doesn't select everything perfectly.  How do I refine the mask created when using that preset?   

Thank you for any help.

The Adpative Blur presets can be refiened in the same way as you refine any blur. Go to the Lens Blur panel, toggle open the Refinement section of the panel as shown in atached screenshot, then refine the blur as required.

Thank you very much, that is what I needed.
